We have obtained a deep i-band image of the blazar 3C 279
while the target was in a low optical state. Due to the faintness of
the optical nucleus we have made the first detection of the host
galaxy. The host galaxy has an apparent I-band magnitude of 
and an effective radius of (
) arcsec. The
luminosity of the host galaxy MR = -23.8 is consistent with
the luminosities of other radio-loud quasar host galaxies. Using the
empirical correlation between bulge luminosity and central black hole
mass Mbh we estimate 
,
broadly consistent with values obtained by photoionization methods.
